ref coolant light

[mercman111]

ive had my manifold off the clk,put it back together and now i have a warning message,coolant visit workshop,why do i have this

 

[Botus]

left a sensor off?

let some coolant out.... what's the level like

 

[mercman111]

no sensor off,level to the top

 

[mercman111]

ive let someout no luck

 

[Botus]

so long as you think the level is right and there's no air where there shouldn't be, can you go in diagnostics tell it to go away and see what happens... in today's world I can imaging it noticed you disconnected it and wants dealer tools to turn it off

 

[mercman111]

i have put my 980 on and it says no fault codes

 

[Botus]

is your tool up to date…. can't have that message without an error.... unless there a software bug and a module needs flashing with an update

 

[mercman111]

how do i update it

Hi, did you measure the amount of coolant that you re-filled it with ? if not the cooling system may not actually be full they are prone to getting air locked when they have been completely drained.

[mercman111]

ive deleted it and it comes straight back on

Check Engine temp sensor too

Looks like a diagnostic session is required.

 

[Botus]

how do i update it

ah you mean the scan tool ?

not sure, some need subscriptions, I don't have one of that type, but all these tools get small software tweaks now and then

I had that message a while back, coolant sensor in bottle was faulty. EDIT. Sorry just remembered it might have been coolant level message?

Left the engine fan disconnected??

it was the engine fan,i must have caught it when i got under the car,so a big thank you to STAR.
